Leon needs bookings. Gloria needs company without a lecture about what she can no longer manage. Their arrangement seems straightforward until she lets her lunch club mistake the actor for her son—and Leon lets the performance continue.

A flat-pack chair, a birthday recording and a dance session bring new clients, new loyalties and a small community-centre show. Then Marcus Beckford arrives to ask why a stranger has been taking his place. As pride collides with affection, Leon must stop improvising other people's relationships and decide what he can honestly offer.

Across eight connected episodes, Someone to Call brings one awkward family deception to a full resolution, with laughter, hard conversations and a very modest stage.
